how to add map box tiles to gmap?

I want to get map box tiles from database but it does not work. I get MBTilesMapProvider class from here.
It is invoked like below:
map.Manager.Mode = AccessMode.ServerAndCache;
map.MapProvider = new MBTilesMapProvider("C:\\Users\\NPC\\Desktop\\test\\ne.mbtiles");
result:
but if google maps used as map provider like below it works well
map.Manager.Mode = AccessMode.ServerAndCache;
map.MapProvider = GoogleSatelliteMapProvider.Instance;
When i debuged i noticed that GetTiles method is invoked never.
Note: I think there is no problem about finding database because it reads meta data from database.

I solved solution by make a bit changes at MBTilesHelper.cs.
First i realized that when reading metadata from database MinZoom and MaxZoom values, they always stay as zero because it does not contain MinZoom or MaxZoom. Therefore, i set them manually.
and secondly i changed a bit "getImage" method.
private PureImage getImage(GPoint pos, int zoom)
{
PureImage retval = null;
var resultImage = _mbtiles.GetTileStream(pos.X, pos.Y, zoom);
if (resultImage != null && resultImage.Length > 0)
{
//resultImage.Position = 0L;
retval = GetTileImageFromArray(resultImage);
}
return retval;
}

Exception when creating Swap Chain with CreateSwapChainForComposition

I am trying to render DirectX12 in SwapChainPanel by using SharpDx but creating a SwapChain fails for an unknown reason. Here is a simplified version of what I have:
// select adapter based on some simple scoring mechanism
SelectedAdapter = SelectAdapter();
// create device
using (var defaultDevice = new Device(SelectedAdapter, FeatureLevel.Level_12_0))
Device = defaultDevice.QueryInterface<SharpDX.Direct3D12.Device2>();
// describe swap chain
SwapChainDescription1 swapChainDescription = new SwapChainDescription1
{
AlphaMode = AlphaMode.Ignore,
BufferCount = 2,
Format = Format.R8G8B8A8_UNorm,
Height = (int)(MainSwapChainPanel.RenderSize.Height),
Width = (int)(MainSwapChainPanel.RenderSize.Width),
SampleDescription = new SampleDescription(1, 0),
Scaling = Scaling.Stretch,
Stereo = false,
SwapEffect = SwapEffect.FlipSequential,
Usage = Usage.RenderTargetOutput
};
// create swap chain
using (var factory2 = SelectedAdapter.GetParent<Factory2>())
{
/*--> throws exception:*/
SwapChain1 swapChain1 = new SwapChain1(factory2, Device, ref swapChainDescription);
SwapChain = swapChain1.QueryInterface<SwapChain2>();
}
// tie created swap chain with swap chain panel
using (ISwapChainPanelNative nativeObject = ComObject.As<ISwapChainPanelNative>(MainSwapChainPanel))
nativeObject.SwapChain = SwapChain;
Selection of adapter works as expected (I have 2 adapters + software adapter). I can create a device and I can see that the app in task manager is using that selected adapter.
Creation of the swap chain is based mostly on this documentation here: https://learn.microsoft.com/en-us/windows/uwp/gaming/directx-and-xaml-interop#swapchainpanel-and-gaming
I get factory2 (with all the adapters and other things enumerated). Constructor of SwapChain1 internally is using factory2 to create a swap chain: https://github.com/sharpdx/SharpDX/blob/master/Source/SharpDX.DXGI/SwapChain1.cs#L64
I compared this method with several others examples and tutorials and this is the way it should be done, however, regardless of the Format I choose or adapter, I keep getting this exception:
{SharpDX.SharpDXException: HRESULT: [0x887A0001], Module:
[SharpDX.DXGI], ApiCode: [DXGI_ERROR_INVALID_CALL/InvalidCall],
Message: The application made a call that is invalid. Either the
parameters of the call or the state of some object was incorrect.

at SharpDX.Result.CheckError() at
SharpDX.DXGI.Factory2.CreateSwapChainForComposition(IUnknown

factory, ComObject device, SwapChainDescription1& description, Output
restrictToOutput) at UI.MainPage.CreateSwapChain()}
DebugLayer doesn't show any additional info.
The app itself is a regular Windows Universal Blank App (min target version Creators Update 15063). I know I can run Directx12 on my current hardware (C++ hello world works just fine).
Any ideas what is wrong?

This is how I got it working:
try
{
using (var factory4 = new Factory4())
{
SwapChain1 swapChain1 = new SwapChain1(factory4, CommandQueue, ref swapChainDescription);
SwapChain = swapChain1.QueryInterface<SwapChain2>();
}
}
catch (Exception e)
{
Debug.WriteLine(e.Message);
return;
}
using (ISwapChainPanelNative nativeObject = ComObject.As<ISwapChainPanelNative>(MainSwapChainPanel))
nativeObject.SwapChain = SwapChain;
So basically I need Factory4 interface to create temporary SwapChain1 from which I can query SwapChain2, then this SwapChain2 can be attached to SwapChainPanel.
Also, a very important thing to notice here is that even though SwapChain1 constructor signature (and documentation) https://github.com/sharpdx/SharpDX/blob/master/Source/SharpDX.DXGI/SwapChain1.cs#L51 says that 2nd argument should be device - it shouldn't. What you need to pass is a CommandQueue object. I have no idea why.
Also, constructor of SwapChain1 says it needs Factory2, but no, you have to pass Factory4!

RallyAPI: How do I create a UserStory and relate it to a Feature?

So, I'm writing an app to 'flesh out' new clients in Rally. It will have tools to create templates which will add first:
add a 'Feature'
add 'UserStories' under that 'Feature'
add 'Tasks' under those 'UserStories' individually
I have figured out step 1. But how to associate anything I can't figure out from the horrible and cryptic documentation. Here's what I have so far:
var FeatureToAdd = _featureRepository.GetFeatures().FirstOrDefault(x => x.Id == 2);
// Initialize the REST API. You can specify a web service version if needed in the constructor.
RallyRestApi restApi = GetRallyRestApi();
//Create an item
DynamicJsonObject toCreate = new DynamicJsonObject();
toCreate["Name"] = FeatureToAdd.Name;
toCreate["Description"] = FeatureToAdd.Description;
// important to which this belongs, but I no ID I ever use works
//toCreate["Workspace"] = "/workspace/" + WebConfigurationManager.AppSettings["RallyAPIWorkspaceID"];
//toCreate["Project"] = "/project/XXXXX";
//toCreate["Iteration"] = "/iteration/XXXXXX";
// create feature - feature is under PortfolioItem
CreateResult createFeatureResult = restApi.Create("PortfolioItem/Feature", toCreate);
// scrape ID off the end of the reference
var pureId = createFeatureResult.Reference.Substring(createFeatureResult.Reference.LastIndexOf('/') + 1);
// add UserStories
foreach (UserStory u in FeatureToAdd.UserStories)
{
toCreate = new DynamicJsonObject();
toCreate["Name"] =u.Name;
toCreate["Description"] = u.Description;
toCreate["WorkProduct"] = "PortfolioItem/Feature/" + pureId;
//toCreate["WorkProduct"] = createFeatureResult.Reference;<- tried this too
// hierarchicalrequirement = UserStory
CreateResult createUserStoryResult = restApi.Create("hierarchicalrequirement", toCreate);
}
Running this creates both, but no association happens. I get a warning:
Ignored JSON element hierarchicalrequirement.WorkProduct during processing of this request.
Why did it arbitrarily ignore this?...

It ignored WorkProduct because WorkProduct is not a valid field on HierarchicalRequirement. The field you want to specify to set the feature parent of a story is called PortfolioItem.
toCreate["PortfolioItem"] = Ref.GetRelativeRef(createFeatureResult.Reference);
Also, object relationships are specified as in WSAPI as refs (/type/id) so you can just directly pass in the reference from the createFeatureResult.
Sorry you're finding the api to be frustrating. It definitely has some weird dark corners but once you use it a bit and get a feel for how the various domain objects are related I think you'll find it to be quite powerful and consistent.

Erasing AutoCAD drawing objects after exploding them, using C#

I am working on a Task in which the code automatically opens a drawing selected by the user [in a UI] and selects all the objects in the drawing and starts to explode all the of them till they cant be exploded anymore. While doing this I face a problem, the original (un-exploded 3D object) is still present in the drawing, super imposed by the Exploded object. Every recursive call of the Explode function creates a new exploded 3D object of that object.
Here is a snippet of the code I working on:
PromptSelectionResult ss = ed.SelectAll();
using (DocumentLock acLckDoc = doc.LockDocument())
{
using (Transaction tr = db.TransactionManager.StartTransaction())
{
objs = new DBObjectCollection();
foreach (SelectedObject so in ss.Value)
{
Entity ent = (Entity)tr.GetObject(so.ObjectId, OpenMode.ForWrite);
if (!(ent is Solid3d))
{
ent.Explode(objs);
ent.UpgradeOpen();
ent.Erase();
}
}
tr.Commit();
}
}
As soon as the control comes on to the ent.Erase() statement - it throws an exception, eCannotBeErasedByCaller. I cant figure out why? I have unlocked all layers, opened the entity for Write, CommandFlags have been set to Session and UsePickSet (shuffled through all).
Anybody got any suggestions?

Looking at your description, you probably need a recursive explode. Sometime ago I did a code around this, for other type of entities, but you can adjust it.
private List<DBObject> FullExplode(Entity ent)
{
// final result
List<DBObject> fullList = new List<DBObject>();
// explode the entity
DBObjectCollection explodedObjects = new DBObjectCollection();
ent.Explode(explodedObjects);
foreach (Entity explodedObj in explodedObjects)
{
// if the exploded entity is a blockref or mtext
// then explode again
if (explodedObj.GetType() == typeof(BlockReference) ||
explodedObj.GetType() == typeof(MText))
{
fullList.AddRange(FullExplode(explodedObj));
}
else
fullList.Add(explodedObj);
}
return fullList;
}
source: http://adndevblog.typepad.com/infrastructure/2013/04/get-cogopoint-label-text.html

I finally found out the reason why the Original objects werent getting erased.
In the earlier part of the code, a AutoCAD Plant3D dwg is exported to AutoCAD (ExporttoAutoCAD / Saveas), this was creating Proxy items. These cant be deleted manually or via code.
Only way is to explode the PipeLines and Inline assets before exporting the file. This happens automatically if you export the file, but if you use saveas, you will have to explode the Pipe components before you export the file.
Wasted a lot of time understanding the cause, but finally got it!

Ektron taxonomy and library items (in v9)

We recently upgraded from Ektron 8.6 to 9.0 (Ektron CMS400.NET, Version: 9.00 SP2(Build 9.0.0.249)).
I have some code (below) which we use to display links to items in a taxonomy. Under 8.6, this would show library items if they had been added to the taxonomy. As of 9.0, it no longer displays library items. It still works for DMS items and normal pages (all first class content in Ektron).
private List<ContentData> getTaxonomyItems(long TaxonomyId)
{
listContentManager = new ContentManager();
criteria = new ContentTaxonomyCriteria(ContentProperty.Id, EkEnumeration.OrderByDirection.Ascending);
criteria.PagingInfo = new Ektron.Cms.PagingInfo(400); // there's a lot of items and I don't want to page them.
criteria.AddFilter(TaxonomyId, true); // this gets sub taxonomies too :)
List<ContentData> contentList = listContentManager.GetList(criteria);
return contentList;
}
(I would love to simply say to users to use the DMS instead of the library, but we have a security requirement and I'm not aware of a way I can enforce security on DMS items like we can with library items by dropping a webconfig file in the library folder.)
Is this a bug that anyone else has experienced?
Or is there a problem with my code (did an API change in the upgrade to 9.0)?
Thanks.

I ended up emailing Ektron support in Sydney (I'm in Australia), and they said:
I would expect ContentManager to only return content, not library
items – must have been a loophole which is now closed. Taxonomy is the
way to go.
So I used some of the code they provided and came up with the following, which appears to work...
private List<TaxonomyItemData> getTaxonomyItems(long TaxonomyId)
{
List<TaxonomyItemData> list = new List<TaxonomyItemData>();
TaxonomyManager taxManager = new TaxonomyManager(Ektron.Cms.Framework.ApiAccessMode.Admin);
TaxonomyCriteria taxonomyCriteria = new Ektron.Cms.Organization.TaxonomyCriteria();
taxonomyCriteria.AddFilter(Ektron.Cms.Organization.TaxonomyProperty.Path,
Ektron.Cms.Common.CriteriaFilterOperator.StartsWith, GetTaxonomyPathById(TaxonomyId));
List<TaxonomyData> TaxonomyDataList = taxManager.GetList(taxonomyCriteria);
foreach (TaxonomyData taxd in TaxonomyDataList)
{
TaxonomyData taxTree = taxManager.GetTree(taxd.Path,
1, // depth. doesn't seem to work. have to manually tranverse lower taxonomies.
true, // include items
null,
Ektron.Cms.Common.EkEnumeration.TaxonomyType.Content,
Ektron.Cms.Common.EkEnumeration.TaxonomyItemsSortOrder.taxonomy_item_display_order);
foreach (TaxonomyItemData taxItem in taxTree.TaxonomyItems)
{
list.Add(taxItem);
}
}
return list;
}
private static String GetTaxonomyPathById(long taxonomyId)
{
TaxonomyManager tMgr = new TaxonomyManager();
TaxonomyData tData = tMgr.GetItem(taxonomyId);
if (tData != null)
{
return tData.Path;
}
return "";
}
This code fetches items for all the child taxonomies as well as returning library items.
The one problem is that it fetches duplicates for some items, but those are easy to clean out.
I was also told by Ektron that...
TaxonomyManager.GetItem(“{path}”) is a more efficient way to get the
categories
That's why I've included the GetTaxonomyPathById() method (inspired by this blog post: http://www.nimbleuser.com/blog/posts/2009/iterating-through-ektron-content-in-multiple-taxonomies-via-directly-interfacing-with-search-indexing-services/ )
